The development of these alternative species offers flexibility and new production opportunities to WSSV affected farms in SE Queensland, and elsewhere in Australia to expand aquaculture production more generally.
Fish health problems are a common cause of aquaculture business failure. In prior pilot trials, significant health challenges were encountered that require thorough veterinary investigation and intervention. The information learnt from investigations can then form components of a health management plan for the culture of these two species in SE Queensland, in various systems. The description of health challenges through veterinary outbreak investigation allows the development and costing of interventions to prevent or treat the issue. Over the 12 month time frame of this project, surveillance strategies can be developed for early detection of disease. Such health management strategies facilitate early response actions that can minimise losses associated with infectious disease.
One metric which influences the viability of aquaculture systems is the density at which a species can be farmed. This is particularly the case in RAS, where the infrastructure capital costs are high. This project will document the impacts of stocking density on health and production in RAS, cages and ponds.
Another element that strongly influences viability of aquaculture enterprises is the growth rates of stock that are able to be achieved. Generating data from systems farmed at commercial densities can assist in determining the suitability of various sites for expansion of farming these species in Australia.
Objectives: 1. Generate data on the production and health performance of Giant Grouper and Cobia in RAS, cages in a saline lake and in outdoor pond growout systems. 2. Field test production outcomes from an experimental recombinant autogenous vaccine for prevention of nodavirus in the Giant Grouper. 3. Assess market potential for various formats of cobia and grouper Read moreRead less

Due to the delayed onset of the condition, infected fish can reach the consumer before soft flesh is detected, causing wastage, economic losses to affected fishers, and loss of consumer confidence.
Rapid onsite detection of myxosporean infection is vital to maximise value of landed fish, minimise environmental impacts associated with animal protein wastage, and increase productivity for NSW commercial fishers, NSW fishers cooperatives and relevant fish markets.
This project focuses on outcome 2 of FRDC’s R&D plan – best practices and production systems. Fast and accurate detection of pathogens help industry identify risks faster and make informed decisions to refine and optimise best practices and production systems. There will be several benefits and impacts on society, environment, and the economy, including:
Society - fisheries productivity affects livelihoods of people working in the industry and its associated sectors - healthy and sustainable food resources Environment - reduce wastage Economic - increasing productivity through higher yields and higher market value - enhancing food/protein production improves food security and creates more employment opportunities Objectives: 1. To develop and evaluate PCR-based diagnostic tools for quantitative detection of myxosporeans in Mahi Mahi and Yellowtail Kingfish 2.

Summary
Ciguatera Fish Poisoning (CFP) causes the largest number of seafood-related food safety incidents in Australia. In NSW and southern QLD waters, CFP is mostly related to Spanish Mackerel (Scomberomorus commerson). Ciguatoxins (CTXs) produced by marine microalgae (Gambierdiscus spp), are polyether toxins that accumulate in fish and cause CFP when fish are eaten. CTXs are heat stable, odourless, tasteless, and toxic at low concentrations, therefore it is very difficult to distinguish toxic fish. In ....Ciguatera Fish Poisoning (CFP) causes the largest number of seafood-related food safety incidents in Australia. In NSW and southern QLD waters, CFP is mostly related to Spanish Mackerel (Scomberomorus commerson). Ciguatoxins (CTXs) produced by marine microalgae (Gambierdiscus spp), are polyether toxins that accumulate in fish and cause CFP when fish are eaten. CTXs are heat stable, odourless, tasteless, and toxic at low concentrations, therefore it is very difficult to distinguish toxic fish. In NSW, since 2014, 31 people have contracted CFP after consuming Spanish Mackerel caught locally, mostly through recreational fishing.
Validated commercial monitoring methods for CTXs are unavailable internationally, although research tools for CTX measurement have been developed. Regulatory methods for CFP prevention are to avoid certain fish species, fish of certain sizes (ie >10kg), or fish from certain regions. In Australia, effective prevention methods have not been clearly evaluated. This results in Spanish Mackerel that are safe to eat potentially being excluded from sale, resulting in significant losses (ie > ~$200k p.a in NSW). This project addresses this issue, which was identified as high priority in the Australian ciguatera research strategy formulated at a recent workshop (27-28th March, 2019).
In 2014, FRDC (Tactical Response) and the NSW Recreational Fisheries Trust funded an initial study on the incidence of CTXs in NSW Spanish Mackerel. CTX was present in flesh and liver samples (1-7% incidence), and was not clearly correlated with the weight of individual fish. This information showed that CFP risk management may require reassessment. This project will advance knowledge by: evaluating methods of detection of CTXs; determining detailed predictive data on CTX incidence; and evaluating environmental and biological factors associated with CTX in Spanish Mackerel to allow for an evaluation of risk assessment strategies. This information will benefit industry by enhancing consumer safety and industry confidence, and enabling the sale of safe Spanish Mackerel.
Objectives: 1. Determine industry CTX needs and conduct of review of available CTX measurement tools (including cell based assays, ELISA kits, and LCMS) against these needs. Conduct an assessment of the currently available screening tools to determine which, if any, hold promise for industry use. Conduct a viability assessment for how a tool might be used in industry or, if none of the currently available tools are appropriate, make recommendations for future activities to develop a rapid screening tool that meets industry needs. 2. Obtain samples of flesh and liver from ~300 individual Spanish Mackerel of all sizes caught in Industry relevant regions of NSW waters over a period of 2 years, as well as length, weight, sex and site information, with the participation of the Sydney Fish Market and commercial fishing Cooperatives. Obtain samples from any individual Spanish Mackerel associated with illnesses in NSW or QLD. Measure CTX1B and other available CTX analogs using best practice methods identified in Objective 1. 3. Conduct statistical data analyses of all available data on CTX concentrations in Spanish Mackerel in comparison to biological and environmental variables.Develop recommended options for food safety risk management for Spanish Mackerel in NSW that will allow for a viable industry while protecting public health.

Summary
Reliable detection of marine biotoxins is a critical requirement for any effective biotoxin monitoring program, requiring any analytical technique to be properly validated. The Neogen rapid test kit for the detection of paralytic shellfish toxin (PSTs) was successfully validated in both single lab and inter-lab validations for use in oysters, offering rapid (within 20 min) on farm results.

The Neogen rapid test kit for the detection of paralytic shellfish toxin (PSTs) was successfully validated in both single lab and inter-lab validations for use in oysters, offering rapid (within 20 min) on farm results. The test was used in Tasmania to reduce business risk, (i.e. frequent testing of shellfish that can rapidly accumulate PST within a week) and employed in South Australia for regulatory purposes (low frequency of PST detection in this region).
A key factor influencing the suitability of antibody based rapid test kits is the PST profile present in the sample to be analysed. The term PST profile describes the relative concentrations of different PST analogues that might be present in each seafood sample. These profiles differ between toxic algal species, different seafood species and their tissues. Not all PST analogues are equally detected by the antibodies of different test kits (quantified as the % cross-reactivity). These cross-reactivities are critical for ensuring reliable detection across different combinations of PST analogues that might be present in shellfish.
To determine if the AquaBC rapid test kit is suitable replacement for routine monitoring, a full validation for each seafood tissue matrix would normally be conducted to determine the probability of detection curve (probability of detection across a range of PST concentrations) for multiple PST profiles, ideally followed by an inter-laboratory validation (as was conducted for the Neogen test). However, a full validation study requires repeat testing of hundreds of samples and is therefore expensive. From our previous work with the Neogen test kit, we have identified some key performance indicators that would allow for a quick initial assessment of the new AquaBC test kit, using much reduced sample numbers. These small pilot trials would include testing the most commonly encountered PST profiles (i.e. which PST toxin analogues are present) and their relative concentrations (i.e. can we reliably detect the presence of PST at the regulatory level without obtaining too many positive results at PST levels below concern?). Rather than conducting a full validation, this project will provide an initial assessment of these parameters in regard to the PST profiles commonly encountered in TAS, SA and NSW. Should this assessment be positive, a full follow up validation may be recommended. Objectives: 1. Review & identify different PST profiles that may be encountered in TAS, SA and NSW oysters. 2. Challenge the AquaBC test kit against a range of different PST concentrations and profiles to provide an initial assessment of its suitability for detecting PST in Australian oyster tissues.

Fins Seafood focus on locally sourced seafood and have the experience and are passionate in this area, solidifying their undeniable importance to be a part of this project.
The project is needed to reaffirm the presence Australian Herring within the seafood market as commercial landings increase over the coming decade. If Australian Herring is successfully marketed, there is a potential for success within the local domestic market and potentially for export, if export approval is granted by the Australian Government. Furthermore, it is designed to address these challenges by providing investment for research, development, and extension initiatives aimed at improving the sustainability and profitability of the Australian Herring fishery. If successful, this proposal aims to obtain an accurate sense of the market appetite and consumer demand, as well as the potential to value-add by using local seafood processors.
Effective marketing through potential branding, introduction of new products and developing the presence of Australian Herring locally will be beneficial to industry and consumers. Furthermore, successful utilisation of all associated fish waste will bring more value and benefit to industry.
Objectives: 1. Identification of the current market demand and future demand forecasts for Australian Herring. 2. Transition Australian Herring from bait to the higher-value human consumption market. 3. Development of three value-add Australian Herring products. 4. Identification of methods of full utilisation of Australian Herring waste products. 5. Development of effective market strategies to introduce value-add Australian Herring products to the retail market. Read moreRead less

The product has traditionally been predominantly used for bait. This project, in partnership with herring producers, processors and retailers, will commence with a historical and current status review and consultation to better understand barriers and opportunities for commercial success of herring products for human consumption. Review of the commercial success or otherwise of similar underutilised species (such as Australian Salmon) will also be included. From this review, it is intended to identify, develop and implement three new retail and/or food service opportunities for herring for human consumption. Such opportunities, informed by the review, may be new product based (incorporating alternate processing strategies and/or 100% utilisation principles) or focussed on new marketing strategies. Evaluation for future commercial success will be economic, logistical and technical and will use evaluation metrics developed in previous projects. An enhanced use of herring for human consumption may not only increase profitability but may also lead to greater stock access for fishers. A framework for improving commercial success of such underutilised species research projects(reported in FRDC 2017/185) may be further extended by the study. Objectives: 1. Identify options to value add and (where possible) fully utilise the Australia Herring through the human consumption market 2. Investigate, implement and evaluate up to three human consumption market opportunities for Australian Herring-based products 3. Document and extend the developed supply chain framework methodology to get proposed new products to the market and explain how it can be replicable for other similar underutilised / lesser-known species Read moreRead less
